EAV REF-COUNT SNAP-SHOT LSB[1] REG [Offset 0X6930]

This LSB and MSB pair captures the EAV Reference Count when externally triggered by the desired TimeSync/
APE_GPIO pin – a toggle serves a trigger. The only legal sequence of accessing this pair is Read-LSB followed
by Read-MSB.

This, concatenated with the Watchdog[0] LSB value,
constitutes a 63-bit value. Precision of the value is
1ns – which equates to the precision of the EAV
Reference Count.
If bit[31] ==1, the desired TimeSync/APE_GPIO shall
toggle as soon as EAV Reference Count[62:0]
increments to match this 63-bit value.
Note: Setting this time value back in time will
produce no toggle.

Write a 1 to enable Time Watchdog[0].
This, concatenated with the Watchdog[0] LSB value,
constitutes a 63-bit value. Precision of the value is
1ns – which equates to the precision of the EAV
Reference Count.
If bit[31] ==1, the desired TimeSync/APE_GPIO shall
toggle as soon as EAV Reference Count[62:0]
increments to match this 63-bit value.
Note: Setting this time value back in time will
produce no toggle.
LSB of the EAV Reference Count as snapshotted by
TimeSync/APE_GPIO [2:0] shall always be 000.
